Sustainability is a hot topic these days. Leaders tout green initiatives. Politicians, actors, and CEOs are now ersatz environmentalists. Perhaps your organization recently jumped on the bandwagon, trying to focus your goals in an "eco" direction. Suddenly you are trying to leave zero carbon footprints and reorient your business plan to take advantage of the new demand for environmentally friendly products. Good for you! The environmental danger to our planet--perhaps the most important issue of our times--and the legacy we leave our grandchildren will largely depend upon how responsible we are about tackling it.
